Need 1 song mastered (alt. rock)

Hey there, my band are currently in the studio recording our debut album.
We would like to have our first single ready to release for April. So we're concentrating our efforts on that song for now. So before getting the rest of the album mastered, we would like to just get this 1 done first.
The music we play is similar to Foo Fighters, Thirty Seconds to Mars, and Biffy Clyro. Quite typical alternative rock. Unfortunately, the full recorded song won't be ready until January.
Looking forward to hearing from you!
